<p>^^ 2 is the magnitude. It’s a vector in polar form, not rectangular.</p>
<p>webass:</p>
<p>Polar coordinates…</p>
<p>I thought it was a point. Could never figured out that problem.
I took 5 practice tests, but never saw a question like that.</p>
<p>Have you seriously never learned vectors? Plus, the angle should have given it away. Even if it was positive 2, the angle points it at quad 3.</p>
<p>what about this negative question?</p>
<p>So far: 2 people, 2 diff answers…</p>
<p>So far I’m a 36 on Math. In English I’m -2, Reading -5/6 (being hard on myself), Science -6/7 (realistic)</p>
<p>My goal is 32.5: so:</p>
<p>M: 36
E: 34
R: 32
S: 30
C: 33.0</p>
<p>and I could still miss 2 points from here. Crossing my fingers…</p>
<p>Maybe in 7th grade.</p>
<p>^^^ Which negative question?</p>
<p>If x and y are both negative real numbers, which one is negative:</p>
<p>I got -(xy)/((X^2) + (Y^2)) </p>
<p>Well, I think thats what it said</p>
<p>That one is correct. x and y are both negative. 2 negs squared are pos. and neg times neg is pos. Negative in front of the fraction makes it negative no matter what.</p>
<p>the answer is quadrant three because polar coordinates take into the form of (r, theta). R being the distance from the origin. and 230 degrees where the line opens up (located). Therefore it is quadrant three due to the fact that 230 degrees is in the 3rf quadrant.</p>
<p>what was the answer to the question asking which geometric shape would make the most different lines when choosing 5 points. i didn’t understand it. i guessed circle cuase there are no sides</p>
<p>do any of you remember the question regarding a circle that had an origin of (-3, 4) (?), and it said something about the radius…what was the answer to that one?</p>
<p>I bubbled in circle because it said geometric figure, not specifically a polygon. If it said polygon than it would be Pentagon because a circle is not a polygon.</p>
<p>the answer was E for the circcle one</p>
<p>Why wouldn’t the 5 inches deep question be 5/9?</p>
<p>do you remember what the value was on the right side of the equal sign?</p>
<p>The circle one with an origin radius 5 was E, (x+3)squ+(x-4)squ=64</p>
<p>^^^ You multiply 5/9 by the height cause 5/9 of the tank is filled.</p>
<p>@anapo: The tank had dimensions 9, 10, and 8. It said that they poured 400 cubic units of water into the tank. How deep was it? okay so NO MATTER what, the area the water covers on the bottom is 80 squared units because 8 X 10 = 80. The 9 was the height of the tank, which you could ignore (the nine). That means you just 400/80 to get the HEIGHT of the water, which is 5.</p>
